LiLo Causing Chaos On “Glee” Set?

The cast and crew of "Glee" are apparently none too happy with Lindsay Lohan's latest shenanigans on the set the Fox series, according to sources at Us Weekly and E! Online.

The actress reportedly showed three to six hours late and was completely unprepared, a source says. The source told E! News, "Lindsay was a total nightmare yesterday. When she did finally arrive, she just didn't want to be there. She did not want to work. She had not memorized her lines, and she kept disappearing so no one could find her."

A spokesman for Lohan confirmed to E! News that she did arrive late to the set, but blamed it all on a "misunderstanding" about the call time.
